A vulnerability was detected in xiweicheng TMS up to 2.28.0. The affected functionality is the Upload function within the file src/main/java/com/lhjz/portal/controller/FileController.java. The manipulation of the argument filename results in unrestricted upload capabilities, which may be exploited from a remote location. The exploit is now public and may be utilized by attackers.
The identified CVSS score for this vulnerability is 2.1, indicating it is categorized as a low-severity issue. However, organizations should still take this vulnerability seriously as it allows for potentially harmful file uploads that can lead to further exploitation or data compromise.
Risk to organizations includes potential unauthorized access or manipulation of system files. Although this vulnerability does not currently appear to be actively exploited, the public availability of the exploit increases the urgency for affected organizations to assess their systems and implement necessary mitigations.
Organizations should prioritize patching this vulnerability as part of their risk management strategy, ensuring that they do not remain vulnerable to potential attacks that may arise from the exploitation of this flaw.
Vulnerability Details
The vulnerability allows for unrestricted file uploads, which can lead to various security threats such as remote code execution or unauthorized access to sensitive data. Officially, this vulnerability has been classified under CWE-284 (Improper Access Control) and CWE-434 (Unrestricted Upload of File with Dangerous Type). The vulnerability was published on January 17, 2026, and is categorized as analyzed.
The CVSS score for this vulnerability is recorded as 2.1, reflecting a low severity and indicating a low attack complexity. The potential impacts on confidentiality, integrity, and availability are assessed as low.
The affected product is the xiweicheng teamwork management system, specifically all versions up to 2.28.0. Organizations using this software should be aware of the implications of this vulnerability and take necessary actions.
Technical Analysis
The root cause of this vulnerability is linked to inadequate validation of file uploads, particularly through the manipulation of the filename argument. Attackers may exploit this flaw by uploading files that can lead to further exploitation of the system.
The attack vector for this vulnerability is network-based, which allows attackers to exploit the flaw remotely. The attack complexity is classified as low, meaning that no specialized conditions are required to execute the attack. Privileges required for successful exploitation are also low, as the attacker needs only to have minimal user access.
There is no user interaction required for the exploitation of this vulnerability, which increases the risk to organizations. The impacts on confidentiality, integrity, and availability are all assessed as low, but the potential for file uploads can lead to greater risks if exploited effectively.
Risk & Impact Analysis
Organizations utilizing the xiweicheng teamwork management system should recognize the real-world risks posed by this vulnerability. The unrestricted upload capability allows attackers to upload malicious files that can compromise the security of the environment.
The urgency for remediation is classified as low due to the low CVSS score, but organizations should still assess their exposure to this vulnerability. The potential blast radius includes unauthorized access to sensitive information or system files, which could lead to significant operational impacts.
